Corrected entry: Only in Germany is a McDonald's Quarter Pounder known exactly as a "Royale with Cheese" ("Royal mit Käse"). The closest otherwise is the French or Portugese "Royal Cheese" but Jules specifically mentions Amsterdam, and a Quarter Pounder with Cheese in Holland is just a Quarter Pounder with Cheese. Many countries which use the metric system don't bother renaming products that use imperial measures. It's a Quarter Pounder with Cheese in Australia, too. Vincent's observation about "Royale with Cheese" being the name of the quarter-pounder with cheese in Amsterdam applies - albeit to Germany, where this has been the official name of the burger for 40+ years.
Corrected entry: When Jackson and Travolta are at the apartment to collect the money from Brett, Jackson comments, "Check out the big brain on Brad," which should have been Brett.
Correction: He says Brett; he just emphasizes the word Brett so it sounds a little like Brad. (Even if he did say Brad it would still only be a character mistake, not a movie mistake.).
He definitely says "Brad," which I have always interpreted as an indication of Jules' indifference to his soon-to-be victim's identity. As if to say, "Brad, Brett... it don't matter much to me because you gonna be dead in about two minutes."
What a great take on the situation. That makes perfect sense.
Question: Why did John Travolta have his gun drawn while talking to the guy in the car who he accidentally shoots?
Answer: He is careless with it, and doesn't think about if it might accidentally fire. There are safety protocols when dealing with guns for a reason. Gangsters just chose to ignore them.
Correction: He was not talking about Amsterdam, but Paris and in Paris they call it a Royale with cheese.
There is no "Royale with Cheese" in Paris. The French are staunch republicans and wouldn't name any product "Royal." The burgers on offer in McDonalds in France cane be seen here, and there is no "Royale with Cheese" anywhere. Https://www.mcdonalds.fr/produits/burgers.
If they don't use the name "Royal" now, they used to. This is the same page from 2017, using archive.org. Https://web.archive.org/web/20170420100607/https://www.mcdonalds.fr/produits/burgers.

Despite your dubious and unsubstantiated claims (your weblink is broken) that the French wouldn't name any product royal, I have been to a McDonald's in France and ordered the 'Royale Cheese' myself, just so I could say so after PF. You can even see it on the menu here also: https://www.quora.com/Do-they-really-have-a-Royale-with-cheese-on-the-McDonalds-menu-in-France.
I just visited https://www.mcdonalds.fr/nos-produits/nos-burgers as of 12/5/2023, and the first 7-8 burgers listed are called "The Royal", including a "Royal Cheese".
